DUMPING-MACHINE.

Specification of Letters Patent.

Patented Feb. 3,1914.

Application filed July 18, 1913. SerialNo. 779,737.

To all whom it may concern Be it known that I, ALFRED E. GRAVES,

V a citizen of the United States, residing at Boston in the county of Suffolk and State of- Hassachusetts, have invented certain new and useful Improvements in Dumping-Vlachines, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof.

This invention has reference to improvements in machines for dumping candy wafers etc., from trays arranged in stack formation and delivering said wafers or articles to receptacles for storage or transportation.

One object of this invention is toso construct a machine of this nature that a series of trays arranged as a stack may be re ceived by the machine and said stack maybe swung from the vertical ultimately to a posit-ion approximately horizontal whereby the articles may slide from said trays into a series of transverse compartments with which one wall of the machine is furnished, said wall being so arranged that the articles may slide laterally from said compartments.

Other objects of the invention will appear from the following description.

The invention consists in the means for receiving articles from a series of groups of the trays arranged in stack form and for delivering the articles without mixing the several groups.

The invention also consists in such other novel features of construction and combination of parts as shall hereinafter be more fully described and pointed out in the claims.

Figure 1, represents a side elevation of the improved dumping machine in the vertical position, in which position the stack of trays is received, parts of the machine being broken away. Fig. 2, represents a perspective view of one of the trays having wafers thereon. Fig. 3, represents an end view of portions of the machine in position as when delivering the articles. Fig. 4, represents a front view of the counter-weights and their guide. Fig. 5, represents a sectional view, taken on line wm Fig. 3 of the dumping machine casing and chute member in the horizontal position.

Similar characters of reference designate corresponding parts throughout.

In the manufacture of sugar wafers, so called, the wafers are stamped or cut from a sheet of material and are delivered or placed on fiat trays a, a usually of wood and having at their side edges the spacing strips 12, b. A truck 0 is used to gather these trays a, a and a single truck may receive trays from several wafer making machines or from a single machine. In case the truck is used to gather trays from several machines said trays will be arranged in groups on the truck each group of trays carrying wafers of a color or flavor differing perhaps from the wafers on the other group of trays and all of said trays are arranged as a vertical stack on said truck. The truck with its stack of trays is or may be moved to a convenient point where the wafers maybe subjected to drying conditions after which or at some other point in the process-of manufacture it is desirable to dump the wafers from the trays without breaking said wafers and, where the stack of trays carries a series of groups of wafers of different characteristics it is or may be desirable to avoid mixing the wafers in the several groups.

In order to efiect the dumping of the very thin and brittle wafers from the trays into receptacles without undue danger of break ing said wafers I have constructed the frame, box or case 5 of a size and shape to recelve a truck 0 Wlt'h' ts stack of trays a, a

. to limit the swinging of said casing.

At the back of the casing 5 is the series of transverse chutes or pockets 8, 8 having open ends, and to the frame member 9 at one side of said series of chutes or pockets is hinged the closure or wall 10 having the transverse compartments 11, 11 formed by the fixed partitions 12, 12 into which are received the pockets 8, 8, the open ends of the compartments 11, 11 being closed by the strip 13 which is hinged to the free edge of the closure or wall 10 which strip when in the closed position is held by the engagement of its loop 14 with the stud 15 on the wall or side 5 of easing 5. On said wall 5' is pivotally mounted the lever 16 which has at one end the sheave 17 carrying the cable 18 the ends of which are secured to the closure or wall 10 so that by the operation of lever 16 said wall 10 may be closed so that the chutes or pockets 8, 8 are received in the compartments 11, 11.

(lasing 5 has the shaft 19, located at a point slightly below the vertical center of said casing, which is mounted in the members 20, 20 of frames 21, 21 so that said casing 5 may be swung from its vertical position to or approximately to a horizontal position in which it is sustained by the leg or support 7. In order to prevent the accidental swinging of case 5 I provide it, at its lower end, with the catch 22 adapted to be engaged by the latch 23 pivotally mounted adjacent said catch. In order to facilitate the swinging of said casing 5 I provide the two part counter-weight 24, 25 slidable in the vertical guide 26 which has the stop 27 adapted to limit the downward movement of weight member 24. To weight member 25 is attached the cable 28 which is free to draw through a bore in member 24 and extends over pulley sheave 29 to the upper end of casing 5 to which it is attached.

It is unnecessary to describe more particularly the remaining features of construc tion as, aside from the specific features above described, any ordinary constructions known in the art may be utilized.

With the casing 5 in the normal position the truck a with its stack of trays a, a is run into place therein whereby the trays a, a are positioned with their spacing strips 5, b at the sides of said casing whereby said trays are open toward the casing wall 10. It is therefore evident that the trays located opposite each of the compartments defined by the pockets 8, 8 can deliver to said pockets only. When the truck 0 and its trays a, a are thus positioned latch 23 is disengaged from its catch 22 and the weights 24, 25 are thus free to slide downwardly and draw the upper end of easing 5 toward sheave 29 carrying said casing 5 toward sheave 29, causing said casing 5 to swing fromits vertical position toward the horizontal, soon after such swinging motion of case 5 has commenced however, weight member 2 is arrested by its stop 26 while weight member 25 is free to continue its downward movement until casing 5 approaches the horizontal position, and the leg 7 rests on the floor and supports the upper end of the casing. Lever 16 is now moved to the release position whereupon cable 17, in its slackening, permits the swinging downward of the free edge of wall 10 and the swinging of the extension member 13 approximately into alinement with said wall. In the swinging movement of casing 5 toward the horizontal the wafers on the trays a, a slide from said trays into the pockets 8, 8 in which they are supported by the bottoms of the compartments 12, 12, defined by the transverse partitions 12, 12 of wall 10 and when the free edge of said wall 10 is dropped the inclination of said wall is such that the wafers in said compartments slide outward from the open ends thereof over the inclined fixed member 30 into receptacles placed to receive them. After the delivery of the wafers from the dumping machine casing 5 may be swung back to its vertical position, latch 23 will engage its catch 22 and hold said casing upright, and the truck 0 with its stack of trays may be removed from said casing and another truck with its stack of trays placed within said casing.

I am aware that casing mounted to swing and adapted to receive a stack of wafer trays for the purpose of dumping the contents of said trays have been known and I therefore do. not claim as my invention such swinging casing broadly but only in combination with a wall or member adapted in one position of the casing to form a chute delivering at the side of the casing.

It is evident that the sides of the frame or casing 5 need not be wholly closed but may be constructed as open frames if desired.

Having thus described my invention I claim as new and desire to secure by Letters Patent.
